Figure 13. An example of all locally powered US2002 intercom stations.
In this example, all components are locally powered using PA-KP local power supplies. Note the use of one termination plug in each intercom channel. (One termination plug is supplied with each US2002.) Only one termination plug should be installed per channel. Typically, they are installed at the first intercom station in the chain. If 2 terminations are installed in a channel, the sound quality and volume level will be noticeably reduced. IMPORTANT!: If a system power supply (SPS2001, PS2001L etc.) is ever connected anywhere in a channel, the termination plug should be removed from that channel, because the system power supply already has built-in termination.
The advantage of locally powered stations is that they can be operated over a greater distance than is possible when using a system power supply.
